Course philosophy

Course philosophy

“[...] the quality of mental process, not the production of correct answers, is themeasure of educative growth[...]” (John Dewey, The Nature of Method, pg. 207)

With the possible exception of pure logical utterances, anything you ever canexpress (i.e. think) about a real world phenomenon will always be an incompleteand inconsistent representation. Moreover, you are in a unique relationship withthe phenomenon and your perspective influences what you articulate.

The essential cognitive process to learning is therefore to deepen and refine yourrelationship by means of a feedback loop that addresses inconsistencies andincompleteness. This loop includes the articulation of (1) what you think and why,(2) how your cognitive model conforms to and how it contradicts observations,and (3) how you should refine your model to better capture the essence of thephenomenon. Your perspective, though unique, can be shared. Thus science isintersubjective, not objective.

The aim of this course is to exercise this mental process and to deepen and refineyour relationship to certain phenomena in experimental physics.

Online consequences

All synchronous classes and office hours will be held through Collaborate Ultra(CU) integrated into CANVAS. Please note that CU lectures will be recorded andposted to CANVAS all recordings will be kept secure, and will only be available tostudents enrolled in the course. Do not distribute recordings of the class sessionsas doing so is a copyright violation as well as violation of your classmates andinstructors privacy.

During this pandemic, the shift to online learning has greatly altered teaching and studying at UBC, including changes to health and safety considerations.Keep in mind that some UBC courses might cover topics that are censored or considered illegal by non-Canadian governments. This may include, but isnot limited to, human rights, representative government, defamation, obscenity, gender or sexuality, and historical or current geopolitical controversies. Ifyou are a student living abroad, you will be subject to the laws of your local jurisdiction, and your local authorities might limit your access to coursematerial or take punitive action against you. UBC is strongly committed to academic freedom, but has no control over foreign authorities (please visithttp://www.calendar.ubc.ca/vancouver/index.cfm?tree=3,33,86,0 for an articulation of the values of the University conveyed in the Senate Statement onAcademic Freedom). Thus, we recognize that students will have legitimate reason to exercise caution in studying certain subjects. If you have concernsregarding your personal situation, consider postponing taking a course with manifest risks, until you are back on campus or reach out to your academicadvisor to find substitute courses.

Course organization and assessment

Course organization

Each student will complete 2 projects. The projects include the following tasks:

1 Define the objectives, timeline, and methods.

2 Perform a literature search.

3 //////Solve////////////////experimental////////////problems/////and//////////acquire///////data. →Numerically simulate in Python aspects of the physics :phenomenon and/or measurement apparatus

4 Process and interpret data. Analysis, fitting and plottingwith Python.

5 Maintain an electronic log book of all work using a PythonJupyter Notebook (see/use https://ubc.syzygy.ca/)

6 Write a scientific paper using LATEX

PHAS workstations have python and texlive system with texmaker editor. OnlineLaTeX Editors exist (e.g. Overleaf).


Course policy

Course policy

There will be up to five students working on a given experiment, however, eachstudent will individually code their own simulations and perform their owndata analysis.

You are encouraged to collaborate and discuss with students working on the sameor similar experiment; however, any simulation results and data analysis that youpresent must be your own. You will submit all simulation and analysis code inyour logbook.

Assessments

Formal discussion (∼ 15 min): oral interview to assess if the student hasunderstood the physics of the phenomenon under study and of theexperimental apparatus (no presentation or write-up required).

Status update (10 min): mid-term assessment of simulations and analysis

Literature review discussion (10 min): to assess whether the student has readand understood at least one Phys. Rev. Lett. (PRL) paper related to project.

Presentation (12+3 min): presentation in front of peers, TAs, instructors.

Logbook: should include explicit work plan for each project, details ofapparatus, theory, simulations made, issues encountered, conclusions drawnfrom analysis, and discussion on errors and uncertainties.

Reduced paper, Experiment 1: scientific paper in Phys. Rev. Lett. (PRL)format including title, abstract, introduction, and figures.

Final paper, Experiment 2: complete PRL paper.

Referee reply, Experiment 2: formal referee reply and revisions

General advice for paper writing and presentations on the course webpage.


Course policy

Schedule

Weekly group discussions are at 2PM (PST) - typicallymondays.

Weekly breakout discussions for each experiment will followgroup discussions.

Instructors and/or TAs are available online MWF from 14h00to 16h00.

A special online mirror slot is tentatively planned forWednesdays from 21h00 to 21h50.

Policies

- If you have a serious problem with meeting any deadline pleasecontact Prof. Madison immediately.- You should meet with a TA or instructor at least once per weekto discuss progress.- Read late policy on website.

Experimental setups

Experimental setups

There are 4 experimental projects available.

List of experiments:

Optical Pumping of Rb atoms

Pulsed Nuclear Magnetic Resonance

Flux of Cosmic Muons

Positron Emission Tomography


Experimental setups

First Step

Read the cover pages of the 4 available experiments athttp://www.phas.ubc.ca/~phys409/

Rank the 4 experiments indicating your preference - assign a total of 40 votesto the four, write the list with votes in article format using LATEX:

Download a temple for Physics Review Letter article.Write the list of experiments in the abstract.Add one figure of your choice to the paper.

and email it to Daniel by this Friday @ midnight. The file should be in pdfformat and the name should start with the student last name followed byunderscore and then phys409 (i.e. madison phys409.pdf).

Example list : Optical pumping (15), Muon Flux (10), Pulsed NMR(10), PET (5).

Experiments will be assigned by next Monday. Additional information will beprovided then.
